Celestron 20x80 - Celestron SkyMaster 20x80mm Porro Prism Binoculars

I had read numerous reviews of these binos being out of collimation but took a chance. They seemed well made and gave me outstanding views of the moon but once I started looking a stars I was getting doubles, I was very disappointed and sent them back. Now I'm afraid to order giant binos and went back to using my Nikon 10x50's.
It's a nice product so why doesn't Celestron address this issue?
Pros: good value
Cons: arrived out of collimation
